I just installed Ubuntu 14.04 32 bit on my Acer netbook.
When I use AutoHide it is hard to get the Launcher to pop up, even with the sensitivity turned all the way up! It seems the "sensitivity" has to do with how fast the mouse moves to the left (I have Launcher on the left), and I almost have to SLAM it over to expose the Launcher.
On this small screen, I want all the space to show, otherwise I can't even have my windows maximized without losing significant real-estate.
Is this feature working properly? Any other suggestions?
